Application led .Tune 26, 1912. Serial No. 706,055.

To all whom 'it may concern Be it known that I, GEORGE E. MAXWELL,

a citizen of the United States, residing at Bronaugh, in the county ofVernon and State of Missouri, have invented new andA useful Improvementsin Upsetting Attachments for Vises, of which the following is aspecification.

This invention relates to devices for shrinking and upsetting tires andthe like, and it has for its object to provide a simple, inexpensive andefficient upsetting device which may be readily applied to and used inconnection with a blacksmiths vise of ordinary construction.

A further object of the invention is to provide a simple and inexpensiveupsetting device which when not in use may be easily and quicklydetached from the vise and stored in small compass.

vVith these and other ends in view which will readily appear as thenature of the invention is better understood, theV same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claim.

In the accompanying drawing has been illustrated a simple and preferredform of .the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theclaim may be resorted to when desired.

In the drawing,-Figure l is a perspective View showing the inventionapplied to an ordinary vise. Fig. 2 is a top plan view showing a portionof a tire applied in position to be operated upon. Fig. 3 is a sideelevation illustrating a modified form of the invention, and alsoshowing a portion of a tire in position to be operated upon. Fig. L is atop view of the same.

Corresponding parts in the vseveral figures are denoted by likecharacters of reference.

The improved upsetting attachment is composed of two members A and Badapted to be mounted, respectively, upon the movable jaw C and upon thestationary jaw D of an ordinary blacksmiths vise, said vise beingequipped with a screw E for forcing the movable jaw in the direction ofthe stationary jaw. The jaws are forced apart in the customary manner bymeans of a spring F. The members A and B are each composed of a baseplate 1, said base i plates being provided adjacent to their inner v ormeeting edges with downwardV extending flanges 2 adapted to engage thefaces of the vise jaws. Each of the base plates l is also providedadjacent to its outer edge with a downwardly extending flange 3 adaptedto rest externally upon the vise which is usually provided with anenlargementor oifset 4 upon which the flange 3 may be supported. In theabsence of such oiset, however, the flange 3 may be supported upon thebody of the jaw.

Under the construction illustrated in Figs. 1 and 2 the base plates lare provided adjacent to one of their side edges with upwardly extendingflanges 5 having teeth or corrugations, as shown at 6. Pivotally mountedupon each of the base plates l near the outer edge thereof is a camlever 7 having a corrugated or toothed engaging face 8 and a handle 9which extends a suitable distance beyond the edge of the base plateopposite to that having the flange 5 so as to be readily grasped by theoperator standing in front of the vise or at one side of the latter.

In the operation of this device the members A and B are placed upon thejaws of the vise, while said jaws are separated or spaced apart, and thetire or article to be shrunk or upset is then placed upon the baseplates l between the flanges 5 and the cam levers, the latter beingactuated to grasp or secure the article between the corrugated faces ofthe flanges 5. The article may be steadied by the hand of the operator,while the screw E of the vise is actuated to force the movable jaw inthe direction of the stationary jaw, thereby causing the article to beshrunk or upset, as will be readily understood.

Under the slightly modified construction illustrated in Figs. 3, l ofthe drawings the base plates here designated l of the members A and Bare corrugated upon their upper faces, said base plates being providedadjacent to one of their side edges with upstanding flanges 5 upon whichthe cam levers, here designated by 7 are pivotally mounted. The handles9 of said cam levers will thus extend upwardly instead of laterally fromthe vise, which may sometimes be found desirable. In other respects theconstruction and operation are precisely as hereinbefore described.

fis will be seen from the foregoing,` desci'iption, the improvedupsetting attachment is extremely simple in construction and is capableo being pi'oduced at a very moderate expense. The said device may bevery readily applied to any oidinaiy blacksmiths vise without the use ofany special fastening` means, and it follows that the device may heapplied o1l detached in a few moments. By this invention, the use of aspecial upsetting machine, the cost o which greatly exceeds that of myimproved attachment, may he dispensed with.

Hating thus described the invention, what is claimed as new, is

lin upsetting device for vises including a noevee pair of base plates,one of the plates being adapted to he disposed upon each jaw of thevise, downwardly extended flanges projectingfrom the inner ends of theplates and adapted to engage the meeting,` faces of the vise, downwardlyextended supporting)- legs projecting from the outer ends of said baseplates and adapted to engage the sides of vise, and clamping levers forsecuring the work to the base plates.

ln testimony whereof l al'lnix my signature in presence of twowitnesses.
